Tx for all the input everybody. I can't find if Rubi do a 115m blade. One helpful tool guy recommended a basic angle grinder blade which would be less aggressive than the normal diamond tipped blade( and woud cost much less, I only have about 20 tiles to cut to this finish quality). The problem is that the blade chips away and doesn't leave a clean edge, whereas he says a slower less aggresive cut would be smoother, if a bit slow. Any views on this ?
